Hi
As said by Bijay u can Go for Blanket Po also.
Create blanket PO with limit and validity period. (Blanket purchase orders have the item category B and the document type FO. )
U can create PO with or without account assignment and can change as per requirement at the time of Invoice verification so that expence will be booked against required cost center
I think this is a best soln.
<b>Also read info given by SAP about Blanket PO</b>
The processing time for individual purchase orders is not often viable for office materials, screws and small parts, cleaning work or lesser services that are required during the course of the year In such cases, you can use blanket purchase orders to procure various consumable materials or services from a vendor, up to a fixed value limit.   
A blanket purchase order contains a validity period and a value limit. This means that you can specify a validity period instead of a delivery date. Invoices can be posted against this blanket purchase order within the validity period. The total invoiced value must not exceed the value limit. A blanket purchase order only contains a short text. It does not contain materials or services. Blanket purchase orders have the item category B and the document type FO.   
You cannot enter a goods receipt, enter services, or accept services for blanket purchase orders.   
<b>The system does not need to know the account assignments for the individual requirements at the time of the purchase order</b>. You can enter them during invoice verification. If account assignment data has already been maintained in the purchase order, you can change these during invoice verification. When you enter an invoice for a blanket purchase order, you can enter as many account assignments as you require, along with the relevant amounts.
